Error handling

Check out the post on error handling by Mika Raento, the researcher at the University of Helsinki, Forum Nokia Champion and the author of the huge amount of free source code examples for Symbian.

Mika talks on the ways of error handling in software and how the developer can aid the error handling:

• You may need to document specific errors and supply additional information to the immediate caller.
• The error information must support generic handling strategies, like a blind retry.
• Low-level exceptions should not be remapped by upper layers.
• The routine detecting an error is responsible for describing it in terms understandable to a human, often the user.
• The system must be able to tell the user if they should contact another human.
• The system must produce different messages for consumption by different humans.
